T 0 all 'whom it may concern:

". Be it known that I, FREDERICK J. 'STUEING, Sr., a citizen of theUnited States,- and resident of White Plains, in the f county ofWestchester and State otllew York, have invented certain new and usefulImprovements in Tree-Repairing Devices, of which the `following is aspecification.

My present invention relates to the thorough and permanent repair ofcavities in trees, and has particular though not exclu- Asive referencetothose of such size or shape as to require a whereby itis divided intosections which may have avlimited relative movement, by means of whichthe 'fillerr is able to sway with the tree in a wind and returnuninjured to its normal position, thus avoiding cracks which wouldadmitj water and cause rot. So much is well known; but the attempt tosolve the problem has generally been by interposing elastic water-proofmaterial between the sections.

In my improvement Iy arrange iron plates,

or plates of other metals, between the s ections and secure them inplace by bolts which are attached to each end of the plate and.

ass through the sound wood on each side of the cavity, approximately ina horizontal plane, the nuts on the'ends being properly y f plate inplace.

protected.

In the accompanying drawings, Figure l is a side elevation partly insection ot a tree repaired by means of my improvement; Figure Q, is aproject-ion of the plate I use; Figure 3 shows one of the bolts.

A is the tree, havinga cavity of some extent, filled with cementconcerete B.' The plates C are shown dividing the ller into sections, asis common in this art. One of the plates is shown in Figure 2, and ispreferably provided with holes c c, enabling the worker to attach boltsD in dierent lengths of plate. Bolts D such as are shown in Figurey 3engage the ends of the plates by means of pins D3, and are insertedthrough the wood at the sides of the opening, being provided withwashers D1 and nuts D2, which are embedded in the wood and protected bya cement iilling E (see Figure l) of any desired waterproof composition.The lowest plate in Figure 1 isl shown in situ, with parts broken awayforV clarity. Ordinarily I employ l iron, making the plates of differentsizes so as to select suitsubdivi'sion in the filler,

able lengths for diierent cavities. of the bolts adjacent to the platesare formed into clevises for ready engagement. n

The arrangement shown has many 'advantages over the criss-cross boltspassing diagonally through the concrete', which are sometimes used. Theplates not only form a surface over which the concrete sections mayslide to the small extent which experience has found to be suiiicient,but form also supporting platformsfon which the concrete may-be putinplace; besides which they may be made in theshop and kept in stock sothat the work is expedited.

immediate repair can save it; and an intervening storm generally meansdestruction. When the cavity is relatively small, onev bolt at each endmay be sufficient, but in general it is better to support the plate bytwo at each end.

I-Iaving thus described my invention, what I claim is:

1. In the art of tree filling, a common means to support independentlyand hold in separated relation an individual sect-ion of a concretefilling for a tree cavity, including a plate extending transversely ofth cavity below the section, and means Jfor connection with the solidpart of the tree to hold the 2. In the art of tree filling, a commonmeans to support independently and hold in separated relation anindividual section of a concrete iilling for a tree cavity, including aplate, extending transversely of the cavity below the section, and meansfor connection with the solid part of the tree to hold the plate inplace, said means including two or more bolts pivoted to the ends of theplate and extending through the solid part ofthe tree at opposite sidesof the cavity; and nuts engaging the bolts.

3. In the art of tree filling, a common means to support independentlyand hold in separated relation an individual'section of a concretefilling for' a tree cavity, including a' plate, extending transversely`of the cavity below the section, and means for connection with the solidpart of the tree to hold the plate in place, said means including two ormore bolts pivoted to kthe ends of the plate and extending through thesolid part of the tree at opposite sides of the cavity; and nuts`engaging the bolts, the plate having margivThe ends Y, y In case of aserious defectappearing 1n aline tree, only i plate in place, said meansincluding tivo or more bolts pivoted to the ends of the plateandfextending through the solid part of the tree at vopposite sides oftthe cavity; and nuts engaging the bolts the plate having Inargi nalopenings at'niteivals -t'or the pivotal connection of the bolt atdilerentfpoints, the
